Is this lip filler infected? (Photo)

Dear milica001,without an examination it is really hard to tell if is it infected. Generally speaking, infected site should be red, painful on palpation, warm, in more severe cases there might be fever. I would recommend you to continue taking your antibiotics and consult your plastic surgeon.Daniel Barrett, MD, MHA, MS

It's difficult to tell from your picture and needs an in-person evaluation. I recommend following up with your Doctor and taking the antibiotics they prescribed. If necessary, this can be reversed with hyaluronidase. It may take a series of treatments. See an expert. Best, Dr. Emer

It is hard to say if this represents infection or a reaction to the filler. It doesn’t appear to be infected, there is no redness. Vobella has been know to have late swelling and nodules and this might be it. This is usually treated with steroids and often needs to be dissolved. This is an immune related response. You must see your provider to assess. Sometimes eating salty foods can cause some mild swelling but this appears more than that.
